ATTACHMENT FOR GRAIN-BINDERS.

Specification of Letters Patent.

Patented Aug. 26,1913.

Application filed August 3, 1912. Serial No. 713,068.

Be it known that I, JAMES T. DRYSDALE,

a subject of the King of Great Britain, re-

siding at North Vancouver, in the Province of British Columbia and Dominion of Canada, have invented new and useful Im provements in Attachments for Grain- Binders, of which the following is a specification.

This invention relates to covers for grain binders, and the particular object of the invention is to produce a combined cover and wind shield of simple and efficient construction.

A further object of the invention is to construct a combined cover and wind shield which may be readily applied to a grain binder of any conventional modern type and which when thus applied may be utilized as a wind shield or as a cover for the grain platform, as may be required.

A further object of the invention is to produce a device of the character described including a spring actuated roller upon which the combined shield and cover will be wound when not in use.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

In the drawings,Figure 1 is a perspective view showing the outline of a conventional grain binder equipped with the invention, the device being applied to the grain platform and to the elevator and the covers being rolled to an out-of-the-way position. Fig. 2 is a top plan view showing the covers extended. Fig. 3 is a rear elevation showing the platform cover extended to form a wind shield. Fig. 4 is a side elevation of the device as seen in Fig. 3. Fig. 5 is a vertical sectional view taken on the line 55 in Fig. 2. Fig. 6 is a vertical sectional view taken on the line 66 in Fig.

3. Fig. 7 is a perspective detail view showing one end of the device.

Corresponding parts in the several figures are denoted by like characters of reference.

The combined wind shield and platform cover 1 is connected with and adapted to be wound upon a roller 2 which is made preferably of sheet metal, said roller constituting a housing for an actuating spring 3 whereby the cover member 4:, which is made of canvas or other suitable flexible, preferably textile material, is automatically wound on said roller. Said cover member is also preferably water-proofed in any suitable manner, for instance, by coating it with oil or with a solution containing rubher. The roller 2 is supported by journals 4: which are associated with the frame structure comprising side members "5, 5 which are provided at their forward ends with L-shaped arms or brackets 8 constituting checks to limit the winding of the flexible cover member 4 upon the roller when the latter is actuated by the spring, said cover member being provided at its free edge with a stop member in the nature of a slat or rope, or the like, which may be suitably at tached at the free edge of the cover member, as indicated at 8'. The side members 5 are preferably made to engage in tubular socket members 9 which are mounted upon a cross bar of the harvester frame, a portion of which is shown at A, said side members 5 being retained in adjusted position in the socket members 9 by means of set screws 10. One of the side members 5 is also provided with an upwardly extending arm 6 provided with a terminal attaching member 7.

The cover member is provided at its front edge with attaching members which are preferably in the nature of rings or links 12. When the device is to be utilized as a apparatus by slipping the rings 12 over the points of said guard fingers, as best seen in Fig. 7.

When the device is to be utilized as a wind shield, one of the links 12 is connected with the terminal fastening member 7 at the upper end of the arm 8 which latter is loca ted at the upper side of the grain platform. An arm or bracket 6 having a terminal fastening member 7 is adjustably mounted on the foot board B of the machine, said foot board being provided with a plurality of apertures 8 for the passage of a bolt or fastening member 9, whereby the arm 6 is adjustably secured. One of the links 12 of the cover member is to be connected with the fastening member 7 of the arm 6, and the cover will thus be supported in extended position at approxi-- mately right angles to the surface of the grain platform. It will, furthermore, be understood that when the device is utilized as a wind shield, the roller may be adjusted to the length of the straw by properly adjusting the side members of the frame structure in the tubular mcmbers9 in which the frame members 5 telescope, correspond ing adjustment of the arm 6 on the foot board B being effected.

The principle of the invention may be applied to the elevator of the binder as well as to the grain platform, as will be seen by reference to Figs. 1 and 2. When thus applied the roller, here designated 14, carrying the cover member, here designated 15, is mounted on the top of the elevator frame where the frame structure carrying said roller may be bolted or otherwise secured. In extending the cover member it is drawn downward over the elevator canvas and under the seat or foot board, the cover mem ber being cut or shaped in such a manner as to meet such obstructions as may be presented by parts of the frame of the machine. The free edge of the cover member is then secured to or connected wit-h the frame structure of the machine by fastening means such as hooks, eyes or snaps l6 engaging parts of the binder frame or coacting members secured on said frame for the purpose.

The improved combined covers and wind shield devices may be very readily and inexpensively attached to a grain binder of any modern conventional type, and when thus applied will be found extremely useful, especially on extensive prairie farms, not only in the event of sudden showers when it is very desirable to pro tect exposed parts of the machine, but also for protecting the machine over night when it is to be left out a distance from the farm center, as is frequently the case, thus saving the time required to cover the ma chine with sheaves of grain, as is now frequently done in order to protect it or the trouble and additional weight of carrying heavy tarpaulin covers, as is occasionally done. The covers may be rendered additionally water-proof and sufliciently efficient to protect machines that are left unhoused over winter by providing additional strips or flaps to be connected with the edges of the cover members and bent, hooked or otherwise connected with the frame structure of the machine to thoroughly protect exposed parts, but such flaps or devices would to some extent have to be patterned according to the particular type of machine to which the invention is applied, and it need not here be described in detail.

Having thus described the invention, what is claimed as new, is

1. A combined wind shield and cover for grain binders having cutting apparatus including guard fingers comprising a spring actuated roller having journals, a frame structure supporting the journals and including an upwardly extending arm, said frame structure being mounted on a binder frame in rear of the grain platform, a flexible cover member connected with the roller, an arm supported on the binder frame, and fastening members at the free edge of the cover member, said fastening members adapted to be connected with the upwardly extending arm and with the arm supported on the binder frame and also with the guard fingers at the front edge of the platform.

2. The combination with a grain binder having a grain platform and cutting apparatus including guard fingers, of a combined cover and wind shield comprising a spring actuated roller mounted adjacent the rear of the platform, supporting means for the same, a flexible cover member connected with the roller, and means for securing the cover member in extended position at various angles with respect to the axis of the roller including means for engaging the guard fingers to hold the cover member extended over the platform.
